We received this notice today as well. We haven't done anything spammy (I know many people say this, but we really haven't). We have a few sites, and only one received this message.

The question is, what do we do now? Has anyone received this message, but nothing has happened? Or was everyone affected when they received this?

Has anyone filed a reconsideration after this, and their site remained ranking fine?
